Benjamin Franklin was right when he wrote: "Nothing can be said
to be certain, except death and taxes." These days, we are not so
sure. The US tax code is not just complicated, it also changes
frequently.

And as shown in this week's chart, US tax revenues are
comparatively low, ranking at the bottom of developed economies
at around a quarter of GDP. Does this mean policymakers will
raise tax rates? What would that mean for your portfolio?
